Electric connection box

Abstract

An electric connection box for connecting a plurality of sub-wire harnesses is disclosed. The electronic connection box comprises a power supply section, a plurality of sub-wire harness connection plates, a plurality of intermediate connection terminals, and a connection section. The power supply section has terminal sections. The plurality of sub-wire harness connection plates are laminated on the power supply section. Each sub-wire harness connection plate has a plurality of set grooves to put electric wires of a sub-wire harness thereinto. Each set groove of sub-wire harness connection plate has a plurality of through holes formed at a bottom thereof and spaced apart from each other in a longitudinal direction thereof. Each intermediate connection terminal is electrically connected to an electric wire of a sub-wire harness and is set in a set groove of a sub-wire harness connection plate so that a through connection conductor connection section thereof is aligned with a through hole of the set groove. The connection section has a plurality of through connection conductors. Each through connection conductor is connected to a terminal section of the power supply section after being inserted through a predetermined through hole in each of the sub-wire harness connection plates and connected to each through connection conductor connection section aligned with the predetermined through hole.
